Vehicle detection method based on optimised YOLOV7 lightweight model / Johan Lela Andika Johan Budiman
No full textThe advancement of unmanned aerial vehicles (UAVs) has encouraged researchers to update object detection algorithms for better accuracy and computational performance. Previous works that apply deep learning models for object detection applications required high graphics processing unit (GPU) computational power. Generally, object detection models suffer trade-off between accuracy and model size where the relationship is not always linear in deep learning models. Various factors such as architectural design, optimization techniques, and dataset characteristics can significantly influence the accuracy, model size and computational cost in adopting object detection models for low-cost embedded devices. Hence, it is crucial to employ lightweight object detection models for real-time object identification for the solution to be sustainable. This work proposes modifications on the head and backbone architecture of YOLOv7-tiny model. Firstly, efficient long-range aggregation network for vehicle detection (ELAN-VD) is incorporated in backbone layer. Secondly, the (UPSAMPLE-VD) on head architecture is improvised resolution to improve the detection accuracy of small vehicles in the aerial image. This study shows that the proposed method yields mean average precision (mAP) of 77.47 %, which is higher than the conventional YOLOv7-tiny of 48.89 %. In addition, the proposed model shown significant performance when compared to previous works, making it viable for application in low-cost embedded devices
Perlindungan penduduk Sipil dalam serangan AS terhadap Irak (tinjauan hukum humaniter: Konvensi Jenewa IV 1949) / oleh Johan Budiman Rollan Napitupulu
No full textSejak terjadinya serangan 11 September 2001, rakyat AS merasa keamanan negaranya terancam. Presiden AS George W. Bush mulai menekankan adanya ancaman Irak terhadap perdamaian dunia karena diduga masih memiliki serta memproduksi senjata kimia dan biologi dan mengembangkan senjata nuklirnya. Bahkan dalam bersama dengan Irak dan Korea Utara sebagai bagian dari "Poros Kejahatan" (Axis of Evil). Bush juga memperingatkan ketiga negara itu bahwa Amerika tidak akan tinggal diam dan tidak akan membiarkan ketiga negara itu mengembangkan senjata pemusnah massal yang dapat mengancam AS. PBB pun tidak tinggal diam menghapi ancaman AS untuk menyerang Irak jika Irak tidak bersedia melucuti senjata pemusnah massal yang dituduhkan AS. Kemudian DK PBB mengeluarkan resolusi 1441 yang memberi kesempatan bagi UNMOVIC untuk melakukan penyelidikan terhadap dugaan adanya adanya senjata pemusnah massal di Irak. Namun, AS tidak puas dan tetap ingin menyerang Irak. Setelah kerangka ressolusi II yang dirancang AS ditolak oleh DK PBB, AS pun mundur dari jalur diplomasi dan akhirnya tetap menyerang Irak pada tanggal 20 Maret 2003. Menurut Konvensi Jenewa IV 1949 penduduk sipil haruslah dilindungi. Namun dalam serangan ini tentara AS tidak hanya menyerang sasaran-sasaran militer, tetapi juga obyek-obyek sipil sehingga menimbulkan korban lebih dari 6.000 penduduk sipil Irak tewas, bahkan lebih banyak lagi yang terluka parah
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
